NEETZoologyEvolution
Which of the following pairs of biological examples and their corresponding evolutionary mechanisms is incorrectly matched?
Options
- AEye of octopus and mammals Convergent evolution
- BVertebrate hearts and brains Convergent evolution
- CAustralian marsupials Adaptive radiation
- DAntibiotic-resistant bacteria Evolution by anthropogenic action
Correct answer
B. Vertebrate hearts and brains Convergent evolution
Step-by-step solution
Vertebrate hearts and brains share a similar basic structural plan but have been modified to perform different functions in different vertebrate classes. They are homologous organs and represent divergent evolution, not convergent evolution. The eye of an octopus and mammals differ in their basic structure but perform the same function, representing convergent evolution. Australian marsupials are a classic example of adaptive radiation, where multiple species evolved from a common ancestor in an isolated geographic
